Multivariate control charts not commonly available in statistical software | Although control charts were originally constructed and maintained by hand, it would be extremely impractical to try to do that with the chart procedures that were presented in Sections 6.5.4.3.1-6.5.4.3.4. Unfortunately, the well-known statistical software packages do not have capability for the four procedures just outlined. However, Dataplot, which is used for case studies and tutorials throughout this e-Handbook, does have that capability. |
